Hong Kong is absolutely incredible. At a Chinese restaurant I used to frequent in Kansas City, there was (is?) an incredible night aerial shot of Hong Kong that covers an entire wall of the restaurant. I used to just sit there and stare it while I ate.
It was somewhat like jetsetter's here, but taken from a high angle looking down where you could see both sides of the bay in the same shot. Completely unreal. I wish I had a copy of it.
Anyway, great thread. Hong Kong is the definition of "urban." Dubai is still just a pretender.
Someday I hope to finally visit.
